Precision 7540 & Precision 7740 owner's thread

Hello everybody 👋 Now i7-8750h and quadro p4200 8gb on my 7730.I saw p5200 16gb for a "tasty" price.Is it any sense to buy it (i mean will my cpu reveal this gpu?),and need i apply other heatsink with it?

Because of the power cap, performance of P4200 and P5200 will be nearly identical in this system. The only reason to upgrade would be if you can make use of the extra VRAM.

And what about rtx4000/5000? Will be necessary other heatsink or i can use default?

Cards from the Precision 7740 can be used, but as is typical with this sort of cross-generation upgrade, you will need an INF mod to load the NVIDIA driver under Windows and that can mess with a small number of games that are particular about driver signatures for anti-cheat purposes.

 

I'm not sure about the heatsink. I don't think a swap is needed but I can't confirm. Carefully check photos of the cards and make sure that screw holes and VRMs are in the same position.

Okay,thanks.By the way,i didn't have any problem with Quadro T2000 on my 7530 (Inf mod) playing Chivalry 2 (from Epic's store,it uses Easy Anti-Cheat).

14% difference i not would call it nearly same performance(both at 100W) but yeah, they r close, n the price difference is huge from P4200 to P5200, for the 14% n double mem u have to pay more then double price 😬 on the other hand, u can cut the TDP from the P5200 to 75W n get the same performance like the P4200 but much cooler n less noisy + double mem. 

 

n still 💩 never a P6000 mobile was out(maybe prototypes), a full GP102 at 100-120W with 24GB would be really nice 🤩

Every benchmark that I saw when these launched put the difference at <5% if there was not VRAM pressure.

P5200 vs. P4200

This seems a bit flaky to me. They don't give details of the system that these tests were run on. There are anomalies like P4200 actually winning their Vulkan test.

 

I'll admit to not digging into the tests here too much, because I already know how it's going to shake out. I've been closely following this line of systems for 15+ years and this is something that has come up for discussion and testing, over and over and over again. There was a lot of chatter about this on NotebookReview at the time of the launch of these systems. Users who had the systems in hand tried different things. P4200 and P5200 were barely different in most cases.

 

This really started to get a lot of attention with the Pascal generation as it started to become clear around that time how NVIDIA was putting very power-constrained desktop-class chips that could "use" a lot more power into laptops, and the power limit was the limiting factor on their performance. But the same has held true with every generation since then, comparing 4000- and 5000- series GPUs from NVIDIA in mobile workstations. It makes sense, given that the architecture and the power limit are the same. Spreading out the load over more cores is going to help with efficiency, but not to the tune of >10% performance. You're welcome to check yourself if you get one in hand.
